BACKGROUND

1. Field of the Disclosure

The present disclosure relates to an optical image capturing lens system, and more particularly, to a compact optical image capturing lens system used in electronic products.

2. Description of the Related Art

The demand for compact imaging lens assembly has grown in recent years as the popularity of portable electronic products with the photographing function has increased. The sensor of a general photographing camera is none other than CCD (Charge Coupled Device) or CMOS (Complementary Metal Oxide Semiconductor) sensor. Furthermore, as the advanced semiconductor manufacturing technology has allowed the pixel size of sensors to be reduced, and the current electronic products are leaning toward a trend of being more compact, there is an increasing demand for higher image quality.

A conventional compact imaging lens system with high image quality equipped on a portable electronic product is often composed of four lens elements such as the lens system set forth in U.S. Pat. No. 8,179,470. However, with the popularity of high level portable electronic products, such as smart phone and PDA (Personal Digital Assistant), the demand for the pixel size and image quality of compact imaging lens system increase fast, and the conventional lens system with four lens elements can no longer satisfy the imaging lens systems of even higher level. Although lens systems adopting five lens elements begin to emerge recently, such as the lens system set forth in U.S. Pat. No. 8,000,030, the lens system struggles in handling the off-axis incident-light so that it tends to have a vignetting effect in the formed image and the relative illumination of the lens system is so low that the image quality becomes undesirable.

In light of the foregoing, an optical image capturing lens system that is suitable for portable electronic devices and has excellent image quality is in need; especially for those whose fifth lens element is configured with stronger positive reflective power, which is favorable for positioning the principle point away toward the image plane. Thus, the angle of incidence from the off-axis field can be effectively controlled for improving relative illumination of peripheral Image and preventing the occurrence of vignetting, which are favorable for improving image quality.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present disclosure provides an optical image capturing lens system, which comprises, in order from the object-side to the image-side, a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element.

The first lens element has positive refractive power, which provides the main refractive power of the system, and thereby the total track length of the system is reduced. When the first lens element has a convex object-side surface, the distribution of the positive refractive power thereof can be adjusted for reducing the total optical track length of the system.

The second lens element has negative refractive power, which is favorable for correcting the aberration produced by the first lens element. When the second lens element has a convex object-side surface and a concave image-side surface, it is favorable for correcting the astigmatism of the system and improving image quality.

The third lens element has positive refractive power, which can reduce the sensitivity of the system. When the third lens element has a convex image-side surface, the spherical aberration can be corrected.

The fourth lens element has a negative refractive power, which can correct the aberration of the system. When the fourth lens element has a concave object-side surface and a convex image-side surface, the astigmatism can be corrected.

When the fifth lens element has positive refractive power, the principle point can be positioned away toward the image plane for effectively controlling the angle of incidence from the off-axis field. Thus, the relative illumination of peripheral Image can be increased and the occurrence of vignetting can be prevented. When the fifth lens element has a convex object-side surface and a concave image-side surface, the astigmatism can be favorably corrected. When at least one inflection point is formed on at least one of the object-side surface and the image-side surface thereof, the angle of incidence onto the image sensor from the off-axis field can be effectively reduced so that the sensing efficiency of the image sensor can be improved and the off-axis aberration can be corrected.

A focal length of the optical image capturing lens system is f. A focal length of the fifth lens element is f5. When the relation of 0.55<f/f5<2.0 is satisfied, by configuring stronger positive refractive power for the fifth lens element, the principle point can be positioned away toward the image plane for effectively controlling the angle of incidence from the off-axis field. Thus, the relative illumination of peripheral Image can be increased and the occurrence of vignetting can be prevented; preferably, the following relation is satisfied: 0.75<f/f5<1.8.

A curvature radius of the object-side surface of the fifth lens element is R9. A curvature radius of the object-side surface of the first lens element is R1. When the relation of 0<R9/R1<1.7 is satisfied, the distribution of the positive refractive power can be balanced for reducing the sensitivity of the system; preferably, the following relation is satisfied: 0.2<R9/R1<1.3.

An Abbe number of the fourth lens element is V4. An Abbe number of the fifth lens element is V5. When the relation of 0.2<V4/V5<0.6 is satisfied, the chromatic aberration of the system can be effectively corrected.

An axial distance between the fourth lens element and the fifth lens element is T45. An axial distance between the third lens element and the fourth lens element is T34. When the relation of 0<T45/T34<0.35 is satisfied, the interval distances between lens elements are proper for the assembly of the lens system and the manufacture yield rate thereof can be improved.

A central thickness of the second lens element is CT2. A central thickness of the fourth lens element is CT4. An axial distance between the second lens element and the third lens element is T23. An axial distance between the third lens element and the fourth lens element is T34. When the relation of 0.5<(CT2+CT4)/(T23+T34)<0.9 is satisfied, the manufacture yield rate can be improved.

A focal length of the fourth lens element is f4. A focal length of the second lens element is f2. When the relation of 0.1<f4/f2<0.85 is satisfied, the aberration can be favorably corrected.

A curvature radius of the object-side surface of the second lens element is R3. A curvature radius of the image-side surface of the second lens element is R4. When the relation of 0.05<(R3−R4)/(R3+R4)<0.5 is satisfied, the astigmatism can be reduced and the aberration can be corrected for improving resolution.

A focal length of the optical image capturing lens system is f. When the relation of 0.1<Yc51/f<0.7 is satisfied, it is favorable for reducing the angle of incidence onto the image sensor from the off-axis field and further correcting the aberration of off-axis field.

A curvature radius of the object-side surface of the fourth lens element is R7. A curvature radius of the image-side surface of the fourth lens element is R8. When the relation of −0.5<(R7−R8)/(R7+R8)<−0.1 is satisfied, the astigmatism can be effectively corrected.

An axial distance between the first lens element and the second lens element is T12. An axial distance between the second lens element and the third lens element is T23. When the relation of 0.02<T12/T23<0.4 is satisfied, it is favorable for lens elements assembly and improving manufacture yield rate.

A central thickness of the fourth lens element is CT4. A central thickness of the fifth lens element is CT5. When the relation of 0.1<CT4/CT5<0.40 is satisfied, it is favorable for the molding and manufacture of lens elements, which is also favorable for obtaining good image quality.

In the aforementioned optical image capturing lens system, the lens elements can be made of glass or plastic materials. If the lens elements are made of glass, the freedom for distributing the refractive power of the optical image capturing lens system can be increased. If plastic material is adopted to produce the lens elements, the production cost will be reduced effectively. Additionally, the surfaces of the lens elements can be aspheric and easily made into non-spherical profiles, allowing more design parameter freedom which can be used to reduce aberrations and the number of the lens elements used in an optical system. Consequently, the total track length of the optical image capturing lens system can be effectively reduced.

In the present optical image capturing lens system, there can be at least one stop provided, such as an aperture stop, a glare stop or a field stop. Said glare stop or said field stop is for eliminating the stray light and thereby improving the image resolution thereof.

In the present optical image capturing lens system, an aperture stop can be configured as a front stop or a middle stop. A front stop can provide a longer distance between an exit pupil of the system and an image plane, and the image-sensing efficiency of an image sensor can be improved. A middle stop is favorable for enlarging the field of view of the system and thereby provides a wider field of view for the same.

According to the optical image capturing lens system of the present disclosure, each of an object-side surface and an image-side surface of every lens element has a paraxial region and a peripheral region. The paraxial region refers to the region of the surface where light rays travel close to an optical axis and the peripheral region refers to the region of the surface where light rays travel away from the optical axis. Particularly, when a lens element has a convex surface, it indicates that the surface is convex at the paraxial region and when the lens element has a concave surface, it indicates that the surface is concave at the paraxial region.

A critical point is referred as a tangential point on a surface of the lens element concerned where the corresponding tangent through the critical point is perpendicular to the optical axis. Please refer to FIG. 11. A vertical distance with respect to the optical axis 1101 between a critical point 1102 on the object-side surface 1151 of the fifth lens element 1150 and the optical axis 1101 is Yc51; wherein the critical point 1102 is not on the optical axis 1101.

The present optical image capturing lens system can be optionally applied to MEMS (Micro-Electro-Mechanical System) focusing and zoom optical systems. In addition, as the optical image capturing lens system has the advantages of superior aberration correction ability and finer image quality, it is suitable for applications in imaging systems such as 3D (3 dimensional) image capturing, digital cameras, portable devices, digital tablets and etc.

Preferred embodiments of the present disclosure will be described in the following paragraphs by referring to the accompanying drawings.
